Genius (but an airhead) who works on genetic engineering x his crush for a decade who works on medical machines. The story is mostly supernatural cause it involves future in genetics. The uke was bugging the seme for his sperm the entire life, he's also someone who has researched on getting pregnant himself. He really likes the seme so him asking the seme for his sperm is not for him to gey pregnant with his baby but to get some DNA since he believes the seme is perfect in all ways.
A one night stand happened after the uke was drunk (he has a habit of asking and spamming the seme with questions asking for his sperm) so the seme got pissed off and taught him a lesson (through sex). He thought that the uke would regret it but the uke really likes him. The seme also ended up getting interested with the uke. Unfortunately the uke forgot his egg project so he got pregnant accidentally and the seme is yet to know
